					Project Vision and Scope Document

Project Name:                      Read ‘n Say
Team Members:1                     Dave         (leader: design and development)
                                   Sam          (developer)
                                   Hannah       (web site and documentation)


Background to the Project

The project is to build an iPhone application that reads text in images captured with the camera.
The text is read in a spoken voice in the native language of the user which is specified in a settings
dialog. The image text is assumed to be in the script and language which is most commonly used at
the current locale of the phone.

The project builds on Dave’s twenty years of experience in image processing and OCR and more
recently on Dave and Sam’s expertise in developing in Cocoa and Objective-C 2.0 on the Mac and iOS
platforms. The software would also run on the new iPod Touch, and on the next generation of iPad.

The project was undertaken as it offers the prospect of a very high return on capital invested.

The Stakeholders

    •   Dave/Jane:       The company (Legentis Ltd) is owned in equal shares by Dave and Jane.
    •   Sam & Hannah: Employed as contractors on the projected and have a stake in the success
        of the business in the form of equity. They receive 5% of the company if it has a turnover of
        more than £1 million per annum at the end of its 2012 financial.
    •   Apple: Apple will gain revenues of about £5 million per annum if the business proceeds to
        plan. The product is also likely to offer them a competitive advantage over other
        manufacturers.
    •   Google: The Google translation software will be used and this may require a license fee if
        large volumes of use are generated.

The Users

The device should provide an easy-to-use and convenient translation service to tourists.

It is anticipate that a suite of more sophisticated products will be produced for business users.

Risks

       •   It is known that Nokia and Google and academic teams in Germany and the USA are working
           to produce similar products. There is a risk that they will produce a better product or take
           some market share.
       •   There is a risk that our device will be reverse engineered and stolen by a competitor who will
           then market the technology as their own.
       •   There is a risk that large companies will issue law suits for patent infringement against
           Legentis. We are confident that the design does not infringe any patents but the cost of
           defence may well be damaging or even prohibitive preventing sales in the USA.
       •   There is a technical risk that the performance may not be adequate for user acceptance.
       •   There is a technical risk that an adequate algorithm will be infeasible given the memory and
           processor speed limitations of the iPhone. This might be ameliorated by running the
           application on a server using the phone for image capture, compression and speech
           generation.
       •   Arabic and Chinese may prove difficult and expensive to read in comparison with Latin
           characters.

Assumptions

       •   That the application will not require a great deal of user support beyond a web page
           with FAQs.

       •   That compiled Objective-C is challenging to reverse engineer.

       •   That the task can be carried out with the existing staff in a timescale of eighteen
           months.

       •   That no further financial resources are required beyond salaries for the development
           team.


Vision of the Solution

Vision statement2

We envisage the device being used as follows: An American tourist in Iraq would be able to hear
Arabic notices and menus read in English while a Chinese tourist in Paris would hear French
documents spoken in Cantonese.

A successful application of this kind is likely to enjoy a mass market (about 50 million iPhones have
been sold and this is increasing at about 5 million a quarter) and could be sold with minimal
overheads on the App store. A 2% market penetration at a £10 sale price would generate net sales
revenue of £16 million per annum and would be likely to lead to license deals with other phone

    The Vision statement might well read much like the most typical Use Case.
manufacturers. This would value the company at about £200 million and attract bids from major
companies thus offering investors a profitable exit strategy.
